To allfwhom 'Lt may concern:

Be it known that we, 'EDWARD NEWTON Mintsl and Gronau `W. SMITH,citizens of the nited States, residing at San Francisco, in fthe countyof San Francisco and State of California, have invented certain newanduseful Improvement-s in Print-ing- Presses, Aof which the following is aspecififcation'. This invention relates to in'iprovements in printingpresses. A l

The object of the invention is to provide an improved feeder for thepaper enabling a much larger pile offpaper to be placed in l5 the feedbox, While at the same tintjeI per mitting the lowest sheet to be takenfrom said feed box; in which the motion of the feed box can be adjustedto correspond with different Widths of paper; which will containimproved means for taking the paper frcn the cylinder; also imprvedmeans for 'raising thefplaten; and'in which' saidlatter means. will berendered in-operative when the sheet of paper is not taken.A

ln the accompanying. drawings,l Figure 1 is a side elevation of theprinting press, certain parts being broken away; Fig. Q'is a similarview at the opposite side; Fig. 3 is a broken plan view; Fig. 4 is anend view 30' of the machine; Fig. '5 is a broken plan View of the diskin one ofits positions; Fig'. 6 1s a similar view in another position;Flg. 7 is a detail perspective view ofthe feed box. Referrin' to thedrawing, 1 represents a suitable frame, having side pieces, 2' and'grooves in said side pieces', `in which the bed? 4 reciprocates. v

represents the driving shaft which recei `ves,its motion from a drivingwheel 6, said' shaft having a bevel pinion 7 meshing with a bevel gear 8on a` vertical shaft 9 carrying at its upper end a disk 10. Upon theupper surface of said`disk is secured a wrist pin.11, whichis-connect'ed by a linki I2 pivotall'y connected, as shown at 13, with.an arm 14 extending from the front end of ,the beth-:that 'is at theend at which the paper is fed". By'therot-ary mot-'ron of said disk areciprocating'- i'notion is imparted'to 'an the bed 'Thewrist pin 11i'slsecured to..

' the disk adjustably, by means of a radialgl'ot 15, injgs'ai'd disl'x,vwhereby'` length `of the stroke can be .increased or diminished asrequired.

As will be presently explained ther cylin'- 515 der 16 is given areciprocating motion from the reciprocating motion of the bed, but inthe opposite direction thereto,- so that when the bed reaches itsfarthest point at the rear end of the mach-ine, the' cylinder has also60 reached its farthest` point at the front end of the machine ready totake the paper.

An important feature ofA this invention is the arrangement of the diskrelatively to the machine. As shown in Figs. 3"- an-d 4, said 65 disk isset to one side of the center, the object being to cause the cylinder tomake a pause at the end of its movement to the front end of the machineWhere it tak'es the paper but to make a qu-ircl( return from the otherend of the machine after delivering the paper. By providing for thispause, the feed ofthe paper is rendered more certain, and the machinecan be run at a higher' speed with sufficient certainty of taking thepaper. One important part of the construction for producing this pauseis, that the Wrist pin is attached to the disk near its edgeso as' to befarthest from the feed endof the machine at the time when, thecylinderhas reached vthe feed endfof the machine, that is,

into the position shown in Figfffi.. On7 the other hand, when thecylinder his reached the delivery end, where a quick return isdesirable, the Wrist pin has passed intol the position nearest the feedend of the. machine, as shovvn at Fig. 5. The advantage of this'construction is that, inthev firstcase, the motion of the bed at'thattime` is derived from the difference of the two longitudimill motions ofthe .wrist pin, the onev due to its swinging about its pivotalconnection 13 with the bed as' a center, and the' other due to itsSwingin about the centerv ofthe disk as a center. or a givensmalla-ngular moa' 95.

tion, there will be a certainl longitudinal movement of the Wrist pinrelative to the 'point '13, lessthan the former' movement,

and it is the difference ofrthesetwo move ments that produces the motionof the bed.- relatively to the center of the disk, when the arts' are inthe position shown in' Fig; 6,

ut their when in the position shown in 5i In the lformer position, thismotion -the latter comparatively large.

of the bed relatively to the disk is small; in

By adjusting the relative dimensions of the distance of the ,wrist pinfrom the center of the disk and its distance from its connection 1.3with the bed, so as to make them more or less equal, the pauses may bemade greater or less, as desired. By making these distances very nearlyve,ual the pause may be made great at the end of the movement of thecylinder at the feed end of the machine. 'Ve have herein shown thisadjustment as being accomplished by increasing the distance of the Wristpin from the center ofthe disk, thus making the two distances morenearly equal to each other, but itis obvious that it may be accomplishedby adjusting the connection of the link 12 with the bed. A. stillfurtherv feature of the construction, which causes this pausev at thedelivery end of the machine is that the disk 10 vis set to one' side ofthe' center of the machine, namely, to the side from'which the wrist pinis traveling at the time when the cylinder is at itsfeed end. In conseuence, the line between the.

centers of the isk. and the point 13 of attachment of the link to thebed is not parallel with the longitudinal direction of t-he machine, butmakes a slight angle therewith, and, it being when the link andtheradius to the wrist pin are `in line with one another that the lon'tudinal movementl of the wrist pin relative yto the disk and bedbecomes zero and changes to; an oppositedirection, it is at this pointthat the motion of the bed ceases', but, from' that point'on, thelongitudinal motion of the wrist pin due to its rotation about the point13 and about the center of the disk, respectively are in oppositedirections and thus counter-balance each other.' The longitudinal motionofthe wrist pin due to its rotation about the center of the disk is thentoward the delivery end of the machine but is reversed at an earlierpoint than is the motion of the wrist indue to itsrotationabout the oint13 an when said reversal takes place t esemotions coun-- terbalance eachother, thus producing a longer pause inthe cylinder at its feed end,Said bed carries on each side a rack 17 with which mesh gear wheels 18secured upon the ends of the cylinderl. Said cylinder has a' shaft 19,thev ends of which are `mounted in -boxes 20 which travellin guides' 21formed upon the frame 1.` On the ends of said shaft 4 19,0utside saidboxes, are mounted smaller gear wheels 22, which mesh `with stationarracks` 23, mounted upon the frame, the effect of this' constructionbeing' that vwhen the bed is moved longitudinally in one directionthe'cylinder rotates and also moves bodily in the opposite` direction. f

Attached to thebed andfmovin'gtherewith 58A, said racks engaging sewheel 27, rotated by means of a dog 28, carried upon a swinging frame29,upon the shaft of the inking roller, said frame 29, in the movement ofthe bed, being adapted to `engage with some stationary` part of theframe, thereby causing the frame to tilt and the dog to drop by gravityinto engagement Awith the ratchet wheel, imparting rotation to theinking roller so as to ink tle surface of thesame.

36 are distributing rollers which are carried by frames 37 attached tothe boxes 20 of the cylinder.

40 represents the -angle -rollers which are `mounted upon the frame,such as are in common use, and having rotary and also longitudinalmovement therein.

The'paper feed box Fig. 41 consists of a back 42 adjustably attached bymeans of a bracket 43 and a set screw 44 to a web 45, forming the bottomof the box, which has a number of undercut` grooves 46 to receive guides47 beneath whichthe web slides. Said back has downward lextensions of{ingers 143 which entend between said guides and prevent the paperworking underneath the back. To said back are also adjustablyatta'ched'iby means ofslots' 48 in they back and set screws 49, sidepieces 50 which can` be moved to and from each other to correspond withthe width of the paper being fed. The guides v4T are all attached attheir front end to a stationary cross piece 51, the front edge of whichis arranged behind, but as close as possible to, the line of suctionholes 81 in the cylinder 16- by which, as hereinafter described, thepaper is caused to adhere to' the cylinder.` The pile of paper is placedon the guides, being impelled thereto by the' motion of s aid back. Toimpart said motion,

theweb 45 has secured thereto, by screws 53,A

side pieces 54, which kare adjustably secured byslots-55 and screws 56to arms 57 of racks ent gears 59 on upon these guides, the back of thepile restlevers 60 pivoted onthe rame of the machine, as shown at 61 andhaving short depending arms 62 pivotally attached to links 63, the otherends of which are suspended vfrom hangers 64 swinging from the. frame,by means of studs passing through holes `66 in the lower 'ends of saidhangers and also .passing into holes 145 in the sides of the links.'Said links are formed on their under s ides, with notches 67, which areadapted to be' enga ed by lugs; 68 on the outwardly 'extending eet'69 ofAhangers 7 0 attached to the bed of the machine, 4and in the motion ofthe bed toward the feed end of the machine, said lugs, engaging saidnotches, carry with the bed said linksin the direction of isan inkfountain 25, in which revolves an "the feed end ofthe machine, therebyimpart-- inking roller which is actuated' by av ratchet ing a rockingmotion to said segment gears swinrin from said han ers 64 which'`describes an arc Iof a circle, and thus cause ,the notches to be raisedfrom olf the lugs and y to be no longer engaged thereby, so that theforward movement ceases, andthe bed moves on without carrying with itthe links, and consequent-ly the forward movement of the feed box stops.

In order -to adjust the extent of forward movement for paper ofdilierent sizes, the holes 1&5' in the sides of the linksare provided incircular series, Vand by selecting holes which are more or'less distantfrom the upper .edgesl ofthe links the amount of feedof the paper willbe lessor more as may bey desired, this arising'from ithe fact that ifthe links be connected with the'hangl ers whenthestuds are inserted inthe holes near the upper edges, then the hangers being already more2oblique', Vtheir upward motion will more-rapid, than from the positionshown in F ig. 2 and consequently the notches ;will be sooner releasedfrom the lugs.

' vAs the pile vof paper fed forward the front edge of the lowest isheetof the pile is drawn toward the cylinder by suction. This cylinder1 isof the same construction as that shown in the patent to E. N. Mills No.785821 issuedMarch 28th, 1905, and therefore need` not be moreparticularly described. Exhaust is suplied to said cylinderby means of apump 72 operated by an eccentric 7 3, on the main shaft, a piston rod74, a pipe 75 y leading from saidpump to an exhaust reser- Voir 76, thelatter communicating with the cylinder by means of a pipe 78 which maybe either Wholly flexible, o r partly lexible and 'have a flexiblejoint, as shown at 79. In like manner as insaid patent, there isprovided a suitable valve 80 for opening the exhaust when the cylindervarrives at the position to take the paper, this position beingl thatshown in Fig. l3, and, when the cylinder begins. its forward movementcarrymg with it the paper, the front'nedge of which has been caused toadhere to the cylinder by suction hrough the holes 81, a cam 82 beingprovided to operate'the. valve and cut off the exhaust as soonas thegripper-s'grip the edge of the paper vand lhold itto the cylinder. Noneof the mechanism relating -to thel construction of the cylinder or themeans of holding the' paper thereto is novel in this application, but wereferto the above patent granted to E. N. Mills for the constructionused herein.

Along thefront of the box 4 -1 is provided a reciprocating jogging board82 supported .i by pair of rods'88 and hinged .thereto at 82X at itsupper edge. The jogging board is normally held against the paper pilevby springs 83 which are'supported in position by the studs 84.

149 indicates. a st'op, comprising a screw,

mounted in a bracket 14% fixed to some stationary part ofthe frame. Theystop envgages with a stud or projection on the end of 'the' joggingboard and operates` to throw the latter -open along lower edge andrelease/a sheet of v.paper from vthe paper pile at the-instantthesuction holes of the cylinder arrive at .this-point. v

- The lower edge is cut out as shown at 85 to pass over wedges 86,located in front of the jogging board 82 and upon va stationary part ofthel machine, said wedges serving to raise the paper, as the lowestsheet is being taken olf, to relieve said lower sheet, and to permit therear edge thereof to be pulled easily from underneath the pile, vwhen,the cylinder has made almost its complete revolution. The lower edge ofthe front side is vcut out to pass between the wedges in order to engageand aline the front edges of the pile, and, particularly at the bottomof the pile. Y

It will be funderstood that in all eases the .Speed ofbox issubstantially equal to that o the cylinder, so that the pile of sheetsmoves with substantially the same velocity as that of the lowest sheet,so that no force is required to move said lowest sheet as it is beingdetached from the remaining she-ets of the pile, and inasmuch as theweight of the pile is then taken by the wedges 86, there is no weightonthe lowest sheet, and therefore itis possible'to put a'large pile ofpaper in the feed box.

When the bed 'returns after a paper sheet vhas been printed and`delivered to the delivimportant that this movement should be startedwithout shock or jar to the feed box. For this purpose there is securedon each side of the bed a depending hanger 70, carrying a4 cylinder 107closed at one end except for a small hole through which passes a pistonrod. 108, the other end of which is loosely attached tothe link 08, andwhich has secured thereto a flange 109 which acts as apiston andagainstwhich a coiled spring 110 abuts. As the bed returns this piston entersthe cylinder 107 and compresses the air therein, which forms a cushion.Moreover themovement ofthe piston is resisted by the compressing of'the' spring 110, a loose washer being mounted on the rod 108 in frontof the said.` springywhich engages with the end of the cylinder. ln thisway the motion of the bed is connnunicated tol the link gradually andresiliently through the spring of the compressed air and of the metallicspring. Therefore by the time that the lug 68 carried by the hanger 70secured to the bed has reached the notch 67 in the lower edge of thelink 63, said link has attained aspeed almostapproaching that of thebed. The lug has been moving against the lower edge of the link, sothat, as soon A as said lug reaches said notch, the link is forced downby the hanger 64, and the notch drops on to the lug.

By reason of the spring of the compressed air and the metallic spring,the link has attained substantially the same velocity as the bed whenthe engagement of the notch and bed takes place, so that thereis nosudden increase of. velocity and `no jar to the feed box casing'by anysuch sudden increase. It has already been explained how upon the returnmovement the notch is lifted from oft' the lug by the circular movementof the j hangers. At the same time in order to absolutely insure thatthe carriage should reach the same place at the saine time, there isprovided on the link a stud 113 which engages an angle piece 114 uponthe bracket, so that the. bed and the link move absolutely together.

The arrangement of thefeed box is such that very narrow'paper can beprinted, because the front edge of the stationary bottom of the feed boxis arranged very near to the front wall of the feed box, so that a verysmall portion ofv the paper is unsupported at any time, and there is nodanger of the paper sagging in a wide unsupported place as is generallythe case with other machines.
